Moreover, while the system and method in the present disclosure is described primarily in regard to allocate a set of sharable orders, it should also be understood that this is only one exemplary embodiment. The system or method of the present disclosure may be applied to any other kind of on demand service. For example, the system or method of the present disclosure may be applied to transportation systems of different environments including land, ocean, aerospace, or the like, or any combination thereof. The vehicle of the transportation systems may include a taxi, a private car, a hitch, a bus, a train, a bullet train, a high speed rail, a subway, a vessel, an aircraft, a spaceship, a hot-air balloon, a driverless vehicle, or the like, or any combination thereof.

One or more of the above positioning systems may be used interchangeably in the present disclosure.

An aspect of the present disclosure relates to online systems and methods for finding sharable and/or combinable transportation transactions, such as carpooling. The systems and methods may do so by determining matching information of a plurality of orders, determining a set of sharable orders based on the matching information, and allocating a set of sharable orders. The matching information may include at least one of a variation in travel direction of the service provider which has accepted the first transaction request when the service provider goes to an origin of a transaction request, direction information, route information, a matching probability or a ratio between an estimated travel time associated with the combined transportation service and an estimated travel time associated with the first transportation service.

It should be noted that online on-demand transportation service, such as online carpool service, is a new form of service rooted only in post-Internet era. It provides technical solutions to users and service providers that could raise only in post-Internet era. In pre-Internet era, when a user hails a taxi on street, the taxi request and acceptance occur only between the passenger and one taxi driver that sees the passenger. If the passenger hails a taxi through telephone call, the service request and acceptance may occur only between the passenger and one service provider (e.g., one taxi company or agent). If a driver wants to provider a carpool service, the driver has to ask a passenger face to face and determine whether the carpooling service is possible to be provided to the passenger by experience of the driver. Online carpool service, however, obtains transaction requests and finds combinable transaction requests in real-time and automatically. The carpool service also allows a user of the service to real-time and automatic distribute a service request to a vast number of individual service providers (e.g., taxi) distance away from the user and allows a plurality of service provides to respond to the service request simultaneously and in real-time. Therefore, through Internet, the online on-demand transportation systems may provide a much more efficient transaction platform for the users and the service providers that may never met in a traditional pre-Internet transportation service system.

FIG. 1 is a block diagram of an exemplary on-demand service system 100 according to some embodiments.

FIG. 2 is a schematic diagram illustrating exemplary hardware and software components of a computing device 200 on which the server 110, the requestor terminal 130, and/or the provider terminal 140 may be implemented according to some embodiments of the present disclosure. For example, the processing engine 112 may be implemented on the computing device 200 and configured to perform functions of the processing engine 112 disclosed in this disclosure.

The computing device 200 may be a general purpose computer or a special purpose computer, both may be used to implement an on-demand system for the present disclosure. The computing device 200 may be used to implement any component of the on-demand service as described herein. For example, the processing engine 112 may be implemented on the computing device 200, via its hardware, software program, firmware, or a combination thereof. Although only one such computer is shown, for convenience, the computer functions relating to the on-demand service as described herein may be implemented in a distributed fashion on a number of similar platforms, to distribute the processing load.

The computing device 200, for example, may include COM ports 250 connected to and from a network connected thereto to facilitate data communications. The computing device 200 may also include a central processing unit (CPU) 220, in the form of one or more processors, for executing program instructions. The exemplary computer platform may include an internal communication bus 210, program storage and data storage of different forms, for example, a disk 270, and a read only memory (ROM) 230, or a random access memory (RAM) 240, for various data files to be processed and/or transmitted by the computer. The exemplary computer platform may also include program instructions stored in the ROM 230, RAM 240, and/or other type of non-transitory storage medium to be executed by the CPU 220.

Merely for illustration, only one CPU and/or processor is described in the computing device 200. However, it should be note that the computing device 200 in the present disclosure may also include multiple CPUs and/or processors, thus operations and/or method steps that are performed by one CPU and/or processor as described in the present disclosure may also be jointly or separately performed by the multiple CPUs and/or processors. For example, if in the present disclosure the CPU and/or processor of the computing device 200 executes both step A and step B, it should be understood that step A and step B may also be performed by two different CPUs and/or processors jointly or separately in the computing device 200 (e.g., the first processor executes step A and the second processor executes step B, or the first and second processors jointly execute steps A and B).

FIG. 3 is a block diagram illustrating an exemplary architecture of processing engine 112 according to some embodiments of the present disclosure. As illustrated, processing engine 112 may include a request obtaining unit 310, a provider information obtaining unit 320, an assignment strategy generation unit 330 and an assignment unit 340.

Request obtaining unit 310 may be configured to obtain a transaction request associated with a transportation service from a service receiver. In some embodiments, the transportation service may be a service of taking an object from one place to another in a vehicle. The object may include passengers and/or goods. The vehicle may include a non-motor vehicle (e.g., a bicycle or a tricycle), a motor vehicle (e.g., a car or a truck), a watercraft (e.g., a ship or a boat) and/or an aircraft. For example, the transportation service may be a taxi service or a delivery service.

In some embodiments, the transaction request of the service receiver may include an origin of the transaction request (e.g., a pickup location of a taxi service), a destination of the transaction request, receiver contact information (e.g., a phone number and/or an email address), object information (e.g., the number of passengers and/or the volume of goods), information of whether to agree to combine the transportation service with another transportation service, or the like, or any combination thereof.

Provider information obtaining unit 320 may be configured to obtain service provider information of a service provider. In some embodiments, the service provider information may include a location of the service provider, provider contact information (e.g., a phone number and/or an email address), the name of the service provider, the plate number of the service provider, the capacity of the service provider (e.g., the passenger capacity and/or the goods capacity), or the like, or any combination thereof.

In some embodiments, the service provider and/or the service receiver may use a device to communicate with the on-demand service system 100 through network 120. The device may include a desktop, an All-in-One personal computer (AIO), a notebook, a smartphone, a Personal Digital Assistant (PDA), a tablet, a carputer, a handheld game player, a wearable device (e.g., smart glasses or smartwatch), a virtual display device (e.g., Oculus Rift or Gear VR), a augmented display device (e.g., Google Glass, Hololens), or the like, or any combination thereof.

Assignment strategy generation unit 330 may be configured to generate an assignment strategy associated with combining two or more transportation services into a new transportation service. In some embodiments, the assignment strategy may include a first strategy that is to combine the two or more transportation services into a new transportation service and/or a second strategy that is not to combine the two or more transportation services into a new transportation service.

Assignment unit 340 may be configured to send the assignment strategy to at least one of the service provider or the two or more service receivers.

The modules in the processing engine 112 may be connected to or communicate with each other via a wired connection or a wireless connection. The wired connection may include a metal cable, an optical cable, a hybrid cable, or the like, or any combination thereof. The wireless connection may include a Local Area Network (LAN), a Wide Area Network (WAN), a Bluetooth, a ZigBee, a Near Field Communication (NFC), or the like, or any combination thereof. Two or more of the modules may be combined as a single module, and any one of the modules may be divided into two or more units. For example, the acquisition module 302 may be integrated in the determination module 304 as a single module which may both obtain features of orders and determine matching information of the orders.

FIG. 4 is a flowchart illustrating an exemplary process of a carpool service according to some embodiments of the present disclosure. The carpool service may refer to an arrangement that combines two or more transportation services into a new transportation service. In this disclosure, a carpool service of combining two transportation services into a new transportation service is taken for example. It should be noted that the carpool service of combining two transportation services into a new transportation service is merely provided for the purposes of illustration, and not intended to limit the scope of the present disclosure. In some embodiments, this disclosure may be applied to a carpool service of combining more than two transportation services into a new transportation service.

In step 410, request obtaining unit 310 may obtain a first transaction request requesting a first transportation service. The request obtaining unit 310 may receive the first transaction request from a first service receiver at a first time point.

In step 420, request obtaining unit 310 may obtain a second transaction request requesting a second transportation service. The request obtaining unit 310 may receive the second transaction request from a second service receiver at a second time point.

In some embodiments, the first transportation service and the second transportation service may be of the same type of services. For example, both the first transportation service and the second transportation service may be taxi service. In some embodiments, the first transportation service and the second transportation service may be different type of services. For example, the first transportation service may be a taxi service, and the second transportation service may be a freight shipping service.

In some embodiments, the first transaction request may include a first origin and/or a first destination, and the second transaction request may include a second origin and/or a second destination.

In some embodiments, the first time point may be earlier than the second time point. In some embodiments, the first time point may be later than the second time point. In some embodiments, the first time point may be equal to the second time point.

The first transaction request and/or the second transaction request may include a real-time transaction request, an appointment transaction request, or a pending transaction request. As used herein, a real-time transaction request may be a transaction request that the requestor wishes to conduct the requested transaction (e.g., transportation service) at the present moment or at a defined time reasonably close to the present moment for an ordinary person in the art. For example, a transaction request may be a real-time transaction request if the defined time is shorter than a threshold value, such as 1 minute, 5 minutes, 10 minutes or 20 minutes. The appointment transaction request may refer to that the requestor wishes to conduct the requested transaction at a defined time which is reasonably far from the present moment for the ordinary person in the art. For example, a transaction request may be an appointment transaction request if the defined time is longer than a threshold value, such as 20 minutes, 2 hours, or 1 day. In some embodiments, the processing engine 112 may define the real-time transaction request or the appointment transaction request based on a time threshold. The time threshold may be default settings of the system 100, or may be adjustable depending on different situations. For example, in a traffic peak period, the time threshold may be relatively small (e.g., 10 minutes), otherwise in idle period (e.g., 10:00-12:00 am), the time threshold may be relatively large (e.g., 1 hour). The pending transaction request may be an on-going transaction request which has not yet been accepted by a service provider at the present moment.

In some embodiments, suppose that the first time point is earlier than the second time point, the first transaction request has been accepted by a service provider and the second transaction request has not been accepted, request obtaining unit 310 may obtain a second transaction request of which the origin is in a certain area according to the location of the service provider at the first time. For example, the distance between the second origin and the location of the service provider at the first time point may be less than a first threshold (e.g., 3 kilometer). As another example, if the location of the service provider at the first time point is in, for example, Manhattan, New York City, request obtaining unit 310 may obtain a second transaction request of which the origin is in Manhattan.

In some embodiments, suppose that the first time point is later than the second time point, the first transaction request has been accepted by a service provider and the second transaction request has not been accepted, request obtaining unit 310 may obtain a first transaction request of which the location of the service provider at the first time is in a certain area according to the origin of the second transaction request. For example, the distance between the second origin and the location of the service provider at the first time point may be less than a first threshold (e.g., 3 kilometer). As another example, if the origin of the second transaction request is in, for example, Manhattan, request obtaining unit 310 may obtain a first transaction request of which the location of the service provider at the first time point is in Manhattan.

In some embodiments, if there are no transaction requests in the certain area, request obtaining unit 310 may obtain a transaction request in another area. Additionally or alternatively, request obtaining unit 310 may obtain a transaction request after a period of time (e.g., 1 minute).

Alternatively, request obtaining unit 310 may obtain transaction requests in any area.

In some embodiments, the transaction request may include information of whether the requestor agrees to combine the transportation service with another transportation service. Accordingly, request obtaining unit 310 may obtain a transaction request that agrees to combine the transportation service with another transportation service. However, if the transaction request does not include the information of whether to agree to combine the transportation service with another transportation service, after obtaining the transaction request, the on-demand service system 100 may send a message to the service receiver to determine whether the service receiver agrees to combine the transportation service with another transportation service.

In step 430, provider information obtaining unit 320 may obtain service provider information of a service provider. The location of the service provider may include a first location at the first time point and/or a second location at the second time point. The first location at the first time point may be the location of the service provider when the first transaction request is obtained by request obtaining unit 310, and the second location at the second time point may be the location of the service provider when the second transaction request is obtained by request obtaining unit 310.

In step 440, assignment strategy generation unit 330 may generate an assignment strategy to combine the first transportation service and the second transportation service into a third transportation service.

In some embodiments, the assignment strategy may include a first strategy or a second strategy. The first strategy may include combining the first transportation service and the second transportation service into the third transportation service. It may include the first origin, the first destination, the second origin, the second destination, the service receiver information, the service provider information, or the like, or any combination thereof. Under the second strategy, the first transportation service and the second transportation service may not be combined into the third transportation service. The second strategy may instead include combining the first transportation service or the second transportation service with a fourth transportation service associated with a fourth transaction request. Alternatively or additionally, the second strategy may include assigning the first transaction request or the second transaction request to an idle service provider, i.e., a service provider that is not serving anyone.

In step 450, assignment unit 340 may send the assignment strategy to at least one of the service provider, the first service receiver or the second service receiver.

In some embodiments, assignment strategy generation unit 330 may determine whether two pending transaction requests are combinable. For example, the first transaction request and the second transaction request may be pending transaction requests. In some embodiments, assignment strategy generation unit 330 may determine whether an acceptable transaction request and a pending transaction request are combinable. For example, the first transaction request may be an acceptable transaction request, and the second transaction request may be a pending transaction request. Here, the accepted request may refer to a transaction request that has been accepted by a service provider. The pending request may refer to a transaction request that has not been accepted by a service provider

In some embodiments, request obtaining unit 310 may obtain one accepted transaction request and one pending transaction request. Assignment strategy generation unit 330 may determine whether the two transportation services associated with the two transaction requests are possible to be combined into a new transportation service. If the answer is “yes”, that is, the two transportation service associated with the two transaction requests is possible to be combined into a new transportation service, assignment strategy generation unit 330 may generate the first strategy. If the answer is “no”, that is, the two transportation service associated with the two transaction requests is not possible to be combined into a new transportation service, assignment strategy generation unit 330 may generate the second strategy, and/or request obtaining unit 310 may obtain another accepted request and/or another pending request.

In some embodiments, request obtaining unit 310 may obtain one accepted transaction request and more than one pending transaction requests. Assignment strategy generation unit 330 may select a pending transaction request from the more than one pending transaction requests. The on-demand service system 100 may combine the transportation service associated with the selected pending transaction request with the transportation service associated the accepted transaction.

In some embodiments, request obtaining unit 310 may obtain one pending transaction request and more than one accepted transaction requests. Assignment strategy generation unit 330 may select an accepted transaction request from the more than one accepted transaction requests. The on-demand service system 100 may combine the transportation service associated with the selected accepted transaction request with the transportation service associated with the pending transaction request.

In some embodiments, request obtaining unit 310 may obtain two or more pending transaction requests. Assignment strategy generation unit 330 may select one or more first groups of pending requests. The first group of pending requests may include two pending requests with which the two transportation services associated are used to be combined into a new transportation service.

In some embodiments, assignment strategy generation unit 330 may select and determine a service provider to provide the new transportation service to the first group. In some embodiments, request obtaining unit 310 may obtain more than one pending transaction requests and more than one accepted requests. Assignment strategy generation unit 330 may determine one or more second group. The second group may include one pending transaction request and one accepted transaction request. The transportation service associated with the pending transaction request and the transportation service associated with the accepted transaction request may be combined into a new transportation service.

FIG. 5 is a block diagram illustrating an exemplary architecture of an assignment strategy generation unit 330 according to some embodiments of the present disclosure. As illustrated, assignment strategy generation unit 330 may include a matching information determination block 510, a matching result generation block 520, a ranking result generation block 530 and a strategy generation block 540.

Matching information determination block 510 may be configured to determine matching information. In some embodiments, the matching information may be used to determine a candidate transaction request of a service receiver associated with a transportation service that is possible to be combined with another transportation service. In some embodiments, the matching information may include a variation in travel direction of the service provider which has accepted the first transaction request when the service provider goes to an origin of a transaction request, direction information, route information, a matching probability, a ratio between an estimated travel time associated with the third transportation service (i.e., the combined transportation transaction of the first transportation service and the second transportation service) and an estimated travel time associated with the first transportation service, or the like, or any combination thereof.

In some embodiments, matching information determination block 510 may include a plurality of sub-blocks configured to determine the matching information. For example, matching information determination block 510 may include a variation sub-block 511, a direction and route sub-block 513, a matching probability sub-block 515 and an estimated time sub-block 517. Variation sub-block 511 may configured to determine a variation in travel direction of the service provider which has accepted the first transaction request when the service provider goes to an origin of a transaction request. Direction and route sub-block 513 may be configured to determine direction information and route information. Matching probability sub-block 515 may be configured to determine a matching probability. Estimated time sub-block 517 may be configured to determine a ratio between an estimated travel time associated with the third transportation service and an estimated travel time associated with the first transportation service. In some embodiments, matching information determination block 510 may include other sub-blocks configured to determine other matching information.

Matching result generation block 520 may be configured to generate a matching result according to the matching information. In some embodiments, the matching result may be a group of candidate transaction requests of service receivers.

Ranking result generation block 530 may be configured to generation a ranking result according to the matching result. In some embodiments, the ranking result may be a transaction request of a service receiver associated with a transportation service that is used to combine with another transportation service. The transaction request of the ranking result may be selected from the matching result.

Strategy generation block 540 may be configured to generate an assignment strategy according to the ranking result.

FIG. 6 is a flowchart illustrating an exemplary process of generating an assignment strategy according to some embodiments of the present disclosure. In some embodiments, process 600 may generate the assignment strategy in step 440 of process 400.

In step 610, matching information determination block 510 may determine matching information according to the first transaction request and the second transaction request. In some embodiments, the matching information may be used to determine a candidate transaction request of a service receiver associated with a transportation service that is possible to be combined with another transportation service. In some embodiments, the matching information may include a variation in travel direction of the service provider which has accepted the first transaction request when the service provider goes to an origin of a transaction request, direction information, route information, a matching probability, a ratio between an estimated travel time associated with the third transportation service and an estimated travel time associated with the first transportation service, or the like, or any combination thereof. In some embodiments, the matching information may be determined according to at least one of the location of the service provider, the first origin, the first destination, the second origin or the second destination.

In step 620, matching result generation block 520 may generate a matching result according to the matching information. In some embodiments, the matching result may be generated by determining whether the matching information satisfies one or more conditions. For example, if the matching information of a transaction request is the matching probability, the condition may be that the matching probability is higher than a second threshold. If the matching probability is higher than the second threshold, the transaction request may be regarded as a candidate transaction request. As another example, if the matching information of a transaction request is the ratio between an estimated travel time associated with the third transportation service and an estimated travel time associated with the first transportation service, the condition may be that the ratio is less than a third threshold. If the ratio is less than the third threshold, the transaction request may be regarded as a candidate transaction request.

In some embodiments, if request obtaining unit 310 obtains one accepted transaction request and more than one pending transaction requests, matching result generation block 520 may select one or more candidate transaction requests from the more than one pending transaction requests. If request obtaining unit 310 obtains one pending transaction request and more than one accepted transaction requests, matching result generation block 520 may select one or more candidate transaction requests from the more than one accepted transaction requests.

In some embodiments, if there is no candidate transaction request in the matching result, request obtaining unit 310 may obtain one or more transaction requests in another area. Additionally or alternatively, request obtaining unit 310 may obtain one or more transaction requests after a period of time (e.g., after 1 minute).

In step 630, ranking result generation block 530 may generate a ranking result according to the matching result. In some embodiments, the candidate transaction requests in the matching result may be ranked. For example, if the matching information is the matching probability, the ranking result may be the transaction request of which the matching probability is the highest. As another example, if the matching information is the direction information and the route information, a score may be determined according to the direction information, the route information, a weight of the direction information and a weight of the route information. The ranking result may be the transaction request of which the score is the highest.

In some embodiments, if the number of the candidate transaction requests in the matching result is less than or equal to 1, step 630 may be omitted.

In step 640, strategy generation block 540 may generate an assignment strategy according to the ranking result. In some embodiments, a first strategy that is to combine the first transportation service and the second transportation service into the third transportation service may be generated according to the ranking result. A second strategy that is not to combine the first transportation service and the second transportation service into the third transportation service may be generated according to other transaction requests obtained by request obtaining unit 310. The other transaction requests may be combined with a fourth transaction request associated with a fourth transportation service or be assigned to a service provider that is not providing a transportation service.

FIG. 7 is a flowchart illustrating an exemplary process of determining matching information according to some embodiments of the present disclosure. In some embodiments, process 700 may be used for determining the matching information in 610 of process 600.

In this case, the first transaction request may be obtained at the first time point, and the second transaction request may be obtained at the second time point. The first time point may be earlier than the second time point. The first transaction request may be an accepted request at the second time point, and the second transaction request may be a pending transaction request at the second time point.

In step 710, variation sub-block 511 may determine a first route according to the first location of the service provider that accepts the first transaction request and the first destination.

In step 720, variation sub-block 511 may determine a second route according to the second origin and the second destination.

In some embodiments, if there are more than one routes according to the first location of the service provider and the first destination or according to the second origin and the second destination, variation sub-block 511 may select one route that satisfies a condition. The condition may include that the length of the route is the shortest, the traveling time of the route is the least, the traffic lights in the route are least, or the like, or any combination thereof.

In step 730, variation sub-block 511 may determine whether there is any overlapping part between the first route and the second route. If the answer is “yes”, that is, there is at least one overlapping part between the first route and the second route, the process may proceed to step 740. If the answer is “no”, that is, there is no overlapping part between the first route and the second route, the process may proceed to step 770 to generate a second strategy that is not to combine the first transportation service associated with the first transaction request and the second transportation service associated with the second transaction request into the third transportation service by strategy generation block 540.

In step 740, variation sub-block 511 may determine a variation in travel direction of the service provider which has accepted the first transaction request when the service provider goes to the second origin according to the first route and the second route. In some embodiments, the service provider may change the travel direction to pick up the second service receiver from the second origin. As illustrated in FIG. 8, if the service provider is in the location of A₁ when request obtaining unit 310 obtains the second transaction request at the second time point, the variation in travel direction of the service provider may be 180° (e.g., a U-turn) when the service provider goes to the second origin B₁ or B₂. If the service provider is in the location of A₂ when request obtaining unit 310 obtains the second transaction request at the second time point, the variation in travel direction of the service provider may be 0° when the service provider goes to the second origin B₁ or B₂. As illustrated in FIG. 9, if the service provider is in the location of A₃ when request obtaining unit 310 obtains the second transaction request at the second time point, the variation in travel direction of the service provider may be a when the service provider goes to the second origin B₃, and the variation in travel direction of the service provider may be 180−α when the service provider goes to the second origin service provider goes to the second origin B₄. If the service provider is in the location of A₄ when request obtaining unit 310 obtains the second transaction request at the second time point, the variation in travel direction of the service provider may be 360°−α when the service provider goes to the second origin B₃, and the variation in travel direction of the service provider may be 180°+α when the service provider goes to the second origin B₄. It should be noted that the description in FIG. 8 and FIG. 9 is merely provided for the purposes of illustration, and not intended to limit the scope of the present disclosure.

In step 750, matching result generation block 520 may determine whether the variation is less than a third threshold. If the answer is “yes”, that is, the variation is less than the third threshold, the process may proceed to step 760 to generate a matching result by matching result generation block 520. If the answer is “no”, that is, the variation is larger than or equal to the third threshold, the process may proceed to step 770. In some embodiments, the third threshold may be 180°.

In some embodiments, the variation may be determined by a variation model. The variation model may be obtained by training historical data in a period of time. The historical data may be one or more transaction requests associated with one or more transportation services that are successfully combined with some other transportation services. The period of time may include 1 hour, 1 day, 2 days, 1 week, 1 month, or the like. In some embodiments, the variation model may be obtained by using a linear regression model to train the historical data in a period of time. The linear regression model may include a logistic regression model, a support vector machine model (SVM), a least square model, or the like, or any combination thereof. The logistic regression model may be represented as Equation (1) and Equation (2) as below:

$\begin{matrix} {{{P\left( {Y = {\left. 1 \middle| X \right. = x}} \right)} = \frac{1}{1 + e^{{- W}*x}}},} & {{Equation}\mspace{14mu} (1)} \\ {{{P\left( {Y = {\left. 0 \middle| X \right. = x}} \right)} = {1 - \frac{1}{1 + e^{{- W}*x}}}},} & {{Equation}\mspace{14mu} (2)} \end{matrix}$

wherein, in this case, X is a variation variable, and refers to the variation in travel direction of the service provider when the service provider goes to the second origin, Y is a target variable, the equation Y=1 refers that the first transportation service associated with the first transaction request and the second transportation service associated with the second transaction request are combined into the third transportation service, the equation Y=0 refers that the first transportation service associated with the first transaction request and the second transportation service associated with the second transaction request are not combined into the third transportation service, P refers to a probability that the first transportation service associated with the first transaction request and the second transportation service associated with the second transaction request are not combined into the third transportation service, and W refers to a regression coefficient.

In some embodiments, steps 740 and 750 may be performed after step 720, and step 730 may be performed after step 730. In some embodiments, step 710 and step 720 may be performed in any order. Step 710 may be performed before step 720. Step 710 may be performed after step 720. Step 710 and step 720 may be performed at the same time. In some embodiments, process 700 may further include a step of determining whether the length of the overlapping part is larger than a fourth threshold. In some embodiments, step 730 may be omitted.

FIG. 10 is a flowchart illustrating an exemplary process of determining matching information according to some embodiments of the present disclosure. In some embodiments, process 1000 may be used for determining the matching information in 610 of process 600.

In this case, the first transaction request may be obtained at the first time point, and the second transaction request may be obtained at the second time point. The first time point may be earlier than or equal to the second time point. The first transaction request may be an accepted request or a pending request at the second time point, and the second transaction request may be a pending transaction request at the second time point.

In step 1010, direction and route sub-block 513 may determine direction information and route information according to the first transaction request and the second transaction request. In some embodiments, the direction information may include a first direction of the first transaction request, a second direction of the second transaction request, a first angle between the first direction and the second direction, or the like, or any combination thereof. The route information may include a first sharing route, a first original route, a second sharing route, a second original route, the length of the first sharing route, the length of the first original route, the length of the second sharing route, the length of the second original route, a first ratio of the length of the first sharing route to the length of the first original route, a second ratio of the length of the second sharing route to the length of the second original route, or the like, or any combination thereof. In some embodiments, the first original route may be a route from the first origin to the first destination in the first transportation service, the second original route may be a route from the second origin to the second destination in the second transportation service, the first sharing route may be a route from the first origin to the first destination in the third transportation service, and the second sharing route may be a route from the second origin to the second destination in the third transportation service.

In step 1020, matching result generation block 520 may generate a matching result according to the direction information and the route information.

FIG. 11 is a flowchart illustrating an exemplary process of determining matching information according to some embodiments of the present disclosure. In some embodiments, process 1100 may be used for determining the direction information and the route information in 1010 of process 1000 and generating the matching result in 1020 of process 1000.

In step 1110, direction and route sub-block 513 may determine a first direction of the first transaction request, a second direction of the second transaction request, a first sharing route, a first original route, a second sharing route and a second original route according to the first transaction request and the second transaction request.

In some embodiments, a direction of a transaction request may be a vector determined by the origin of the transaction request and the destination of the transaction request, and the direction of the vector may be from the origin to the destination. The first direction may be determined according to the first origin and the first destination, and the second direction may be determined according to the second origin and the second destination.

The first original route may be determined according to the first origin and the first destination. The second original route may be determined according to the second origin and the second destination.

If the on-demand transportation service system 100 determine to combine the first transportation service associated with the first transaction request with the second transportation service associated with the second transaction request, the system 100 may determine a sharing route according to the first origin, the first destination, the second origin and the second destination. The sharing route may include the first sharing route and the second sharing route.

In step 1120, direction and route sub-block 513 may determine the length of the first sharing route, the length of the second sharing route, the length of the first original route and the length of the second original route.

In step 1130, direction and route sub-block 513 may determine a first angle between the first direction and the second direction, a first ratio of the length of the first sharing route to the length of the first original route, and a second ratio of the length of the second sharing route to the length of the second original route. Here, the first ratio may be used to measure the extent of detour of the first transaction request when the first transportation service is combined with the second transportation service, and the second ratio may be used to measure the extent of detour of the second transaction request when the first transportation service is combined with the second transportation service.

In step 1140, matching result generation block 520 may determine whether the first angle is less than a fifth threshold. If the answer is “yes”, that is, the first angle is less than the fifth threshold, the process may proceed to step 1150. If the answer is “no”, that is, the first angle is larger than or equal to the fifth threshold, the process may proceed to step 1180 to generate a second strategy by strategy generation block 540.

In step 1150, matching result generation block 520 may determine whether the first ratio is less than a sixth threshold. If the answer is “yes”, that is, the first ratio is less than the sixth threshold, the process may proceed to step 1160. If the answer is “no”, that is, the first ratio is larger than or equal to the sixth threshold, the process may proceed to step 1180 to generate a second strategy.

In step 1160, matching result generation block 520 may determine whether the second ratio is less than a seventh threshold. If the answer is “yes”, that is, the second ratio is less than the seventh threshold, the process may proceed to step 1170 to generate a matching result by matching result generation block 520. If the answer is “no”, that is, the second ratio is larger than or equal to the seventh threshold, the process may proceed to step 1180 to generate a second strategy.

In some embodiments, step 1140, step 1150 and step 1160 may be performed in any order.

Steps 1110-1130 may be used for determining the direction information and the route information in 1010 of process 1000. Steps 1140-1170 may be used for generating the matching result in 1020 of process 1000.

FIG. 12 is a flowchart illustrating an exemplary process of determining matching information according to some embodiments of the present disclosure. In some embodiments, process 1200 may be used for determining the matching information in 610 of process 600.

In this case, the first transaction request may be obtained at the first time point, and the second transaction request may be obtained at the second time point. The first time point may be later than the second time point. The first transaction request may be an accepted request at the second time point, and the second transaction request may be a pending transaction request at the second time point.

In step 1210, matching probability sub-block 515 may obtain a first parameter according to the first origin, the first destination, the second origin and the second destination.

In some embodiments, the first parameter may include the distance between the second location of the service provider and the first origin, the distance between the second location of the service provider and the first destination, a second angle between a third original route and a fourth original route, a third ratio of the length of a third sharing route to the length of the third original route, and/or a fourth ratio of the length of a fourth sharing route to the length of the fourth original route. The third original route may be determined according to the first origin and the first destination. The fourth original route may be determined according to the second origin and the second destination. The third sharing route may be determined according to the first origin, the first destination and the second origin. The fourth sharing route may be determined according to the second origin, the second destination and the first destination.

In step 1220, matching probability sub-block 515 may obtain a provider weight corresponding to the first parameter. In some embodiments, the provider weight may be obtained according to historical data or empirical data.

In step 1230, matching probability sub-block 515 may determine a matching probability according to the first parameter and the provider weight.

FIG. 13 is a flowchart illustrating an exemplary process of obtaining a provider weight according to some embodiments of the present disclosure. In some embodiments, process 1300 may be used for obtaining the provider weight in 1220 of process 1200.

In step 1310, matching probability sub-block 515 may obtain a third transaction request and a fourth transaction request. In some embodiments, the third transaction request may be associated with a fourth transportation service, and the fourth transaction request may be associated with a fifth transportation service. The fourth transportation service may be successfully combined with the fifth transportation service.

In step 1320, matching probability sub-block 515 may obtain a second parameter according to the third transaction request and the fourth transaction request.

In step 1330, matching probability sub-block 515 may determine the provider weight according to the second parameter. In some embodiments, the provider weight may be determined by a weight model. The weight model may be obtained by training historical data in a period of time. The historical data may be one or more transaction requests associated with one or more transportation services that are successfully combined with some other transportation services. The period of time may include 1 hour, 1 day, 2 days, 1 week, 1 month, or the like. In some embodiments, the weight model may be obtained by using a linear regression model to train the historical data in a period of time. The linear regression model may include a logistic regression model, a support vector machine model (SVM), a least square model, or the like, or any combination thereof. The logistic regression model may be represented as Equation (1) and Equation (2), wherein, in this case, X is a variation variable, and refers to the second parameter, Y is a target variable, the equation Y=1 refers that the first transportation service associated with the first transaction request and the second transportation service associated with the second transaction request are combined into the third transportation service, the equation Y=0 refers that the first transportation service associated with the first transaction request and the second transportation service associated with the second transaction request are not combined into the third transportation service, P refers to a probability that the first transportation service associated with the first transaction request and the second transportation service associated with the second transaction request are not combined into the third transportation service, and W refers to a regression coefficient.

FIG. 14 is a flowchart illustrating an exemplary process of determining matching information according to some embodiments of the present disclosure. In some embodiments, process 1400 may be used for determining the matching information in 610 of process 600.

In this case, the first transaction request may be obtained at the first time point, and the second transaction request may be obtained at the second time point. The first time point may be earlier than the second time point. The first transaction request may be an accepted request at the second time point, and the second transaction request may be a pending transaction request at the second time point.

In step 1410, estimated time sub-block 517 may determine a fifth route according to at least one of the first location of the service provider, the first origin, the second destination, the first origin and/or the first destination.

In step 1420, estimated time sub-block 517 may determine a sixth route according to the second location of the service provider, the second origin and the first destination. In some embodiments, when determining the fifth route and/or the sixth route, if there are more than one routes, estimated time sub-block 517 may select one route that satisfies a condition. The condition may include that the length of the route is the shortest, the traveling time of the route is the least, the traffic lights in the route are least, or the like, or any combination thereof.

In step 1430, estimated time sub-block 517 may determine an estimated time of the fifth route. In step 1440, estimated time sub-block 517 may determine an estimated time of the sixth route. In some embodiments, the estimated time may be determined by an estimated time model. The estimated time model may be obtained by training historical data in a period of time. The historical data may be one or more transaction requests associated with one or more transportation services that are successfully combined with some other transportation services. The period of time may include 1 hour, 1 day, 2 days, 1 week, 1 month, or the like. In some embodiments, the estimated time model may be obtained by using a linear regression model to train the historical data in a period of time. The linear regression model may include a logistic regression model, a support vector machine model (SVM), a least square model, or the like, or any combination thereof. The logistic regression model may be represented as Equation (1) and Equation (2), wherein, in this case, X is a variation variable, and refers to the estimated time of a route, Y is a target variable, the equation Y=1 refers that the first transportation service associated with the first transaction request and the second transportation service associated with the second transaction request are combined into the third transportation service, the equation Y=0 refers that the first transportation service associated with the first transaction request and the second transportation service associated with the second transaction request are not combined into the third transportation service, P refers to a probability that the first transportation service associated with the first transaction request and the second transportation service associated with the second transaction request are not combined into the third transportation service, and W refers to a regression coefficient.

In step 1450, estimated time sub-block 517 may determine a fifth ratio of the estimated time of the sixth route to the estimated time of the fifth route. Here, the fifth ratio may be used to measure the extent of detour of the first transaction request when the first transportation service is combined with the second transportation service.

In step 1460, matching result generation block 520 may determine whether the fifth ratio is less than an eighth threshold. If the answer is “yes”, the process may proceed to step 1470 to generate a matching result by matching result generation block 520. If the answer is “no”, the process may proceed to step 1480 to generate a second strategy by strategy generation block 540.

In some embodiments, step 1410 and step 1420 may be performed in any order. In some embodiments, step 1410 and step 1420 may be performed at the same time. In some embodiments, step 1430 and step 1440 may be performed in any order. In some embodiments, step 1430 and step 1440 may be performed at the same time. In some embodiments, step 1430 may be performed before or after step 1420.

Steps 1410-1450 may be performed by estimated time sub-block 517. Steps 1460-1470 may be performed by matching result generation block 520.
